Re: Ceramic kiln with manual controls (low, Med, High)
The low, medium and high settings control the speed of heating. In actual fact they normally control the percentage of time the power is on. You can achieve any desired target temperature with any of these settings. It will take longer on low than medium.

Re: Unwanted asymmetry when slumping
In my view you both are firing to hot. It is much better to fire low and long. This also will help avoid the marks on the underside of the piece. It sounds to me like this is a fairly shallow mould, so 630C for 20 - 30 mins should be enough. Observe when the glass is fully formed. If it is so before...

Re: Fusing glass to animal skull
I have had some experience of fusing glass over bones. Bones are mostly calcium. Some of that calcium is lost during firing, but not much. very thin bones, like a sheep's shoulder blade fade away at the thin edges. Glass will crack over strong under cuts. If you do not use weathered bones, stay out ...

Re: Fusing 3 layers thin glass?
Use a slower than usual rate of advance. A bubble squeeze is essential.
You might use shards of glass around the edge. You might even cut the glass larger than the final size to cut away the marks of the "chads"

2.5 is the approximate specific graivity of all soda glass. Lead glass and others are different.

Re: Seam with white residue
Borax is the flux. If you are using washing powder borax there may be additives that leave a residue. I would not be washing with borax in any case.

Re: first break in a long time
What is th soak at 371C going to do?
In my view - nothing. It is below the strain point, so no further annealing can be done. The aim to me is to steadily cool the glass to room temperature. The. Soak does not do that.

Re: Silk screen, powders.... enamels etc.
It bothers me that Bullseye charges for this. Not really a particularly wonderful way to support the people who buy their glass, to charge them to see how to use it. I wish Bullseye would reconsider that. No other manufacturer I can think of charges you for ideas on using their products. I find the...

Grind with successively fine sandpaper or diamond pads and water until a luster, then fire polish
